Why not wireless?
But anyway, almost any ADSL Modem/Router would do you, as said. How much are you willing to spend on one? You could get one with wireless connectivity anyway, but turn the wireless LAN stuff off until you need/want it - future proofing...
Anyway, a quick browse of newegg reveals a couple of suggestions (I'm from the UK, but most US folks around these forums seem to shop there)
<A HREF="http://www.newegg.com/Product/Product.asp?Item=N82E16833127062" target="_new">D-Link 504T</A> (But this has 1 negative customer review)
<A HREF="http://www.newegg.com/Product/Product.asp?Item=N82E16833196001" target="_new">Diamond DSL64WLG</A> (Has wireless, but they generally do these days)
The important thing about those is they have an RJ-11 connection for the phone line. If your company supply a simple modem/router with your DSL line which gives a single standard RJ45 network connector, then you might be able to just get a network hub, but here in the UK most home ADSL packages come with a USB ADSL modem.
I haven't used any of those boxes I listed personally. My Experiences are with a crappy single-port Actiontec router/modem (cheap and crap), the Netgear 834G (quite good, quite inexpensive, has wireless and a decent firewall), the Draytek Vigor 2600 (more expensive, but excellent - probably not what you'd want though), and some 3Com wireless router whose model number I've forgotten ('borrowed' it from work to replace my Actiontec POS at home
).
